SPECIFICATION forming part of Letters Patent No. 455,552, dated July 7',1891. Application filed November 3. 189d- Serial No. 370,177. (Nomodel.)

To all whom it nutty concern.-

Be it known that l, EDWIN D. WELTON, of

NVaterbury, in the county of New Haven and 'and exact description of thesame, and which said drawings constitute part of this specification, andrepresent, in

Figure 1, a top or plan view; Fig. 2, a side I view looking from theleft of Fig. 1; Fig. 3, a front View; Fig. 4, a side view of one of thestuds which the machine is adapted toset; Fig. 5, a vertical centralsection of the same; Fig. 6, a sectional view cutting on line 00 0c ofFig. 3, looking to the left and illustrating the mechanism for impartingrotation to the hop per-fingers; Fig. 7, a vertical central section online 00 0c of Fig. 6; Fig. 8, a detached longitudinal sectional View ofthe hopper, illustrating the delivery of the studs from the finger inthe hopper to the conductor leading from the hopper; Fig. 9, adetachedface view of the hopper, showing the conductor and guard and alsoillustrating the operation of the fingers within'the hopper; Fig. 10, alongitudinal section cutting in a vertical central plane through thesetter, showing sectional side view of the slide h, the partsbeing inthe normal or stud-receiving position: Fig. 11, the same as Fig. 10,showing the mechanism as having delivered the stud to the setter; Fig.12, alongitudinal sectional view showing the cams on the drivingshaft;Fig. 13,.a transverse section illustrating the mechanism for operatingthe setter, and Fig. 14 a detached top view looking down upon the setterand the hook-slide.

This invention relates to a machine for setting that class oflacing-studs which consist of a tubular shank having a hook upon itsouter end, the shank being substantially an eyelet, and so that when setthrough a corresponding hole the metal of the shank is .upset upon thereverse side, as in the case of I an eyelet, and so as to firmly securethe hook,

these hooks being specially adapted for the lacing of boots. and shoes,one of such hooks being shown in Figs. 4: and 5, the object of theinvention being the construction of a machine into the hopper of which amass of such hooks may be placed and be successive- 1y deliveredtherefrom to a setting device, the

. maybe supported in any suitable or convenlent manner; B, thedriving-shaft, supported in suitable bearin gs, to which power isapplied to impart revolution thereto from a pulley C. This pulley ispreferably loose upon the shaft, and a clutch D is arranged on theshaft, combined with a lever E, by which the clutch may be thrown intoengagement with the Wheel, so that the wheel will be coupled with theshaft or disconnected therefrom, as may be requireda common expedient inautomatic machinery for applying or disengaging the power.

F 'represents'the hopper, which is supported upon a bracket G,stationary upon the top of the bed A. The hopper has an opening 11 inthe top, and, as here represented, this is closed by a hinged cover I,as seen in Figs. 7 and 8. The hopper is of substantially cylindricalshape, the axis being horizontal. In axial line with the hopper a shaftJ is arranged in the bracket G. This shaft extends into the hopper andcarries several fingers K K. These fingers preferably project from adisk L, made fast to the shaft J; but in any case the fingers areadapted to revolve with the said shaft J. The fingers K are ofblade-like shape-that is, they are of thin metal seinewhat less inthickness than the opening in thehook-and they stand upon an incline tothe axis of the hopper 'and shaft J," so that when one of the fingers isin the up position, as seen in Fig. 8, it will incline downward from theshaft side to the opposite side of the hopper, and at that time thefinger is substantially vertical.

A mass of studs is placed in the hopper and the fingers rotate throughthe mass, and each plane of' the IOO ' through opening M finger in suchrevolution through the mass will enter the open side of one or morehooks and so engage the hooks that the hooks thus engaged will be takenby the finger and carried upward to the position seen in Fig. 8, severalstuds being represented as upon the finger, and the inclination of thefingers with relation to the axis upon which they revolve is such thatthey will slide from the finger, if permitted so to do, by their owngravity. In revolving, as seen in Fig. 8, the finger comes into linewith an aperture M through the side of the hopper, and through which thestuds on the finger may slide, so as to escape from the finger. From theopening M a guide or conductor N ektends, this guide presenting an edgelike the edge of the finger K and in line therewith, so that the studspassing through the opening M in the hopper will run directly onto thesaid conductor N, and this conductor leads to the point where the studsare to be set.

An intermittent rotation imparted to the shaft J and the fingers K,which it carries, and so that as one of the fingers reaches the openingM, as seen in Fig. 8, the shaft will remain stationary for apredetermined length of time, and so as to permit the studs to pass fromthe finger through the opening M onto the conductor N. Such intermittentrotation of the fingers is produced from a cam-groove.

O in the cam 12 on the shaft 13. Loose on the shaft J is a collar P, andthis collar receives an oscillatory movement from the cam O a lever Q,connected to the said disk by a rod R, (see Fig. 6,) and so that in therotation of the shaft B an up-and-down vibratory movement will beimparted to said lever Q and a corresponding osci-llatory'movementimparted to the collar P. The inner face of the collar P is recessed,and within that recess is a toothed ratchet S, made fast to the shaft J,and in a recess T in the collar P in the plane of the ratchet S is apawl U, (see Fig. 6,) which is adapted to engage the teeth of theratchet S.

' A limited amount of friction is applied to the shaft J, as hererepresented. This is produced by a nut V, screwed onto the shaft againstthe side of the bracket opposite the disk L, and so that by the turningup of the nut the requisite friction will be produced. As the collar Padvances under the rise of the lever Q and the engagement therewith ofthe pawl U it will impart a corresponding rotation to the shaft J, andthis rotation is sufficient to advance one of the fingers to the upposition, as seen in Fig. 8, while others are passing through the massof studs below, and when the finger presenting the studs has beenthusbrought to its up position the pawl U is free to return under the actionof the cam 0.

It is necessary to successively arrest the fingers in a positioncorresponding to the and the conductor N, so that the with certaintyslide from the finstuds may ger so presented onto the conductor N.

thus arrest the fingers, a dog WV is hung upon a stationary pivot X,(see Fig. 6,) which is adapted to engage the teeth of a second ratchetY, made fast to the shaft J, and the position of this dog W withrelation to the teeth of the ratchet Y is such that each tooth of theratchet Y will engage the said dog when the up position of the fingersis reached. Therefore the number of teeth of the ratchet Y shouldcorrespond to the number of fingers in the hopper. The dog W isyieldinglyheld against the ratchet by a spring Z.

The operation of thedog WV and the ratchet Y makes a positive stop whena predetermined position of the fingers is attained,and the dog beingarranged, as here represented, upon the side opposite the pawl U, theshoulder or working edge of teeth of the ratchet Y is in the oppositedirection to that of the teeth of the ratchet S, upon which the pawloperates. Because of this dead-lock of the shaft and fingers it isnecessary to mechanically throw the dog I out of engagement with theratchet Y before rotation of the shaft commences. Normally the dog WVstands out of engagement with the ratchet Y, as represented ,in Fig. 6,and it is thus held by means of a concentric slot 0. in the collar P, inwhich a stud b on the dog V rides. At the end of the said slot a towardthe pawl the slot is turned inward toward the ratchet, as at d, and sothat as the collar P rotates under the action of the pawl 'U, as beforedescribed, the dog WV will be held out of engagement with the ratchetYduring the time of passage of the concentric portion of the slot a overthe stud b of the dog W; but so soon as the turned-in portion of theslot reaches the stud b it permits the dog W to spring inward, and thisinward movement of the dog brings it into position to engage the nextadvancing tooth of the ratchet Y, and so as to certainly arrest therotation of the ratchet when the tooth engages the said dog and asrepresented in broken lines in Fig. 6. Then when the collar P, with thepawl U, returns the turned-in or cam-shaped portion d of the slot atforces the dog WV outward and away from its engagement with the ratchetY and ready for the next advance movement of the pawl U, the frictionupon the shaft J being sufficient to prevent the return of the shaftwiththe returnof the collarP. Bythisarrangement of mechanism the fingersin the hopper willbe successively presented to the opening M for theescape of the studs, which may be taken by the fingers through saidopening onto the said conductor N. It is of course necessary that thestuds should be presented with their shanks all in one direction, andthis is accomplished by causing the fingers to run so close to thebottom of the hopper that they can only engage studs which arepresentedwith their shanks upward and with the open edge toward thefingerybut there will always be more or less of the studs in the hopperpresented to the fingers as and the arrow in that figure indicates thedirection of rotation, it being understood that the vertical plane ofthe conductor N corresponds substantiallywith the vertical plane of thefinger when it is presented thereto,

and so that the conductor forms practicallya continuation of the finger.

It at any time the conductor should be so full of studs that allpresented by a finger into line with the conductor could not escapethrough the opening M onto the finger, there would be a liability of"the foremost stud on the finger projecting so far from the finger as tostrike the side of the opening M when the finger commenced its nextadvance step. To prevent such clogging, a deflector d (see Figs. 8 and9) is arranged in the opening and operates upon that side of the openingtoward which the fingers are revolvingthat is, the upper side-andpresents a curved or camlike surface, against which the foremost'stud onthe finger will strike as the finger advances and operate to press thestuds backward onto the finger and out of possible reach of the side ofthe opening;

' Upon the inside of the hopper a concentric recess 6 (indicated inbroken lines, Fig. 9) is formed in the plane of the path of movement ofthe end of the finger and of a depth sufficientto permit a stud toescape from the finger should it turn forward onto the end of the fingerin passing the opening, this being an additional precaution againstpossible clogging. Over the conductor N and following'the line of itsupper or guiding edge a corresponding guard fis arranged, which servesto hold the studs on the conductor-or prevent their accidental escapetherefrom. The conductor N starts from the hopper in a vertical plane,but is twisted, so that when it arrives at the place of setting, as seenin Fig. 9, it stands in a horizontal plane, and so that the studswill bepresented with the shank in a vertical plane shank upward. One of thestuds isshown on the conductor at gin Fig. 9, and the end of theconductor is shown in Fig. 10,in which the stud g is represen ed ashavingescaped from the end of the conductor.

A slide h is arranged in suitable guides 2' on the bed and so as toreciprocate in a plane at substantially right angles to the delivery endof the conductor. (See Figs. let and 10.) A reciprocating movement isimparted to this slide it by means of a cam-j on the shaft B through alever 76, hung upon a pivot Z and connected to the slide 7L by a link m.The

. cam operates upon the slide h positively to produce the rear movement,and a spring it operates in. conjunction therewith to producethe'forward or advance movement of the slide This slide is representedin Fig. 10 as in --its eXt'reme rear position and in Fig. 11 in theadvance or forward position. A t the forward end of the slide" a slottedprojection o is formed,the plane of the projection correspon dingsubstantially to the plane of the. under side of the head of the stud asit comes from the conductor N, and so that the stud may pass from theconductor N onto the projection 0. This projection 0 forms a seat uponwhich the stud may rest. Upon the upper side of the slide it a hook p ishung upon a pivot r, so as. to swing in a horizontal plane. Then theslide is in its rear position,as seen in Figs. l l and 10, this hook pstands directly in the path of the shank portion of the stud, and sothat as the forward stud passes from the conductor onto the seat 0 theshank of the stud will pass into the embrace of the hook, as seen inFig. 10, and sothat the hook will be supported in an upright position onthe seat,

a vertical slide t, and which normally stands in the plane of theopening in the stud as it is presented by the slide h, and as seen inFigs. 10 and 11,but so that after the stud has been so presented andplaced upon thev sett er s a vertical movement may be imparted to thesaid setter. As the stud has been thus placed upon the setter the slideh returns;

but before such return of the slide it is necessary that the hook fromthe stud.

To automatically disengage the hook from the stud, the hook isconstructed with an arm u, projecting laterally therefrom, and on thebed or some part of the machine is a stationary stud 1*, forward of thearm to and in its path and in a position with relation to the said armthat as the hook approaches its extreme forward position it willstrikethe said stud Q; and turn the hook away from the stud, asrepresented in broken lines, Fig. 14, thus clearing the hook from thestud, so that the slide and hook may return, and as the slide and hookso return. the arm it strikes another stationary stud w, and so .as toreturn the hook, as represented in Fig. 9, preparatory to receiving thenext stud. The vertical reciprocating movement is imparted to theslide't, which carries the setter, by means of a cam-2 on the shaft B.(See Figs. 12 and 13.) The setter-slide t is connected to a link 3,which, with the link 4, forms a toggle. From the joint of this toggle abar 5 extends to the. canrand so as to be operated thereby, as indicatedin Fig. 13, and so that under the-rotationjof the cam the toggle will'beoperated to force ,the slide t upward, as seen in broken lines, Fig. 13,or draw the said slide downward.

To hold the stud firmly upon the setter and prevent the possibility ofaccidental disengagement, a dog (5 is hung upon an axis 7.in

p should 7 be disengaged the slide tbelow the setter s andsoas tovi-.

brate in a back-and-forward vertical ptane.

The upper end of this dog is constructed with a recess 8, whichcorresponds substantially to the head of the stud. Normally the upperend of this dog stands to the rear of the setter 3, as seen in Fig. 10;but as the slide h advances the slot in the seat permits the seat topass forward, one portion each side of said dog, and so as to bring thehead of the stud into the recess 8 in the dog, then the slide strikesthe dog, so that the dog then moves forward with the slide and stud asthe stud passes onto the setter s and until the final position isreached, as seen in Fig. 11. As the dog then stands, the stud ispractically looked upon the setter, and the slide retreats and leavesthe dog and stud in that position. To hold the dog in this lockingposition, a spring-follower 9 is arranged in the set-terslide t belowthe dog, and the lower end of the dog is constructed with two seats 10and 11 oblique to each other. The one seat 10 rests upon the follower 9when the dog is in the rear or receiving position; but as the dog isturned, as before described,to the position seen in Fig. 11 the seat 10passes from the In so doing it operates as a cam follower 9. todepressthe follower, and then as the dog reaches its extreme forwardposition the seat ll is brought over the follower, which rises to meetthat seat, as seen in Fig. 11, the springfollower offering sufficientresistance to the turning of the dog to hold it in either position.After the stud shall have been set, as hereinafter-described, the dog isreturned by a cam 12 on the shaft B,operatingaslide 13, arranged to movebackward and forward in the plane of the dog through a lever 14:, hungupon an axis 15. (See Figs. 2 and 10.) This cam normally holds the slide13 in its rear position. The lever 14 is provided with a spring 16, thetendency of which is to force the slide forward, and at one point in thecam 12 is a recess 17, into which the cam end of the lever It may drop,and in so dropping the slide 18 will be advanced, as seen in Fig. 11,and so as to strike the lower or tail end of the dog and give it itsreturn movement.

Over the setter s and in line therewith a setting-anvil 18 is arranged.This anvil, as he re represented, is a spindle supported in a verticalposition in a head 19, stationary in the bed of the machine, and ispreferably made adjustable in the head 19. As here represented, thisadjustment is produced by a screw 20, and when the adjustment is made isheld' by a lock-nut 21. The face 22 of the anvil 18 is shapedsubstantially like the face of an eyelet-setting punch or anvil, and soas to enter the tubular shank of the stud and throw the metal outwardand toward the base of the stud, and so as to clamp the material uponthe stud in the usual manner. The stud having been delivered to andreceived by the setter, as before described, the material to which thestud is to be attached having been punched accordingly is placed overthe shank of the stud, and then the setter rises and takes the stud andmaterial upward to the anvil, where the setting is perform ed. Thesetter and material then returning, the material with the stud thereonis removed, a second stud delivered and in like manner set, and so on,the studs being successively and automatically delivered and set.

Vhile I prefer to produce the setting operation by employing astationaryanvil and moving the setter to it, the setter may remain stationary andthe anvil be moved upward and downward to produce the setting-that is tosay,-the reciprocating movement may be imparted to the anvilorsetting-punch 18 instead of to the setter s-such reversal of themovement being so common in eyelet-setting machines as to be too wellknown to those skilled in the art to which this invention pertains torequire particular illustration and description.

For convenience of clearing the hopper, an opening is preferably formednear the bottom of the hopper and a removable cover 23 is appliedthereto, as seen in Fig. 7.
